It's so weird to think of this name as a feminine name, since it's used only as a male name in Denmark. Furthermore it's very old-fashioned, and I really don't like it at all, and not because of it's old-fashioness.

There's a girl at my school named Orla, and although she's very nice, this name is just much too close to oral (as above posters have noted). It makes me think of being confused (possibly due to the 'or' sound), or of gnawing, for some reason.
